. certain new and usefullmprovements in Machines for Cutting and FormingBinding- Strips, of which the following is aspecification. I

The object of this invention is to provide a machine for the purpose ofcutting and forming metal binding-strips adapted to protect borders ofcalendar-cards or similar articles, and the machine is so arranged thatthe feeding, cutting, and forming of the strips will be entirelyautomatic and accomplished in asiinple, rapid, and perfect manner. Theniachine is further constructed so that the cutting of one strip and theforming of the next preceding strip will be effected by the same strokeof the operating mechanism, thereby performing the two operationssimultaneously and dispensing with separate and distinct devicesindependently operated for forming the strip after the same has been cutfrom a sheet of metal. 7

The invention consists in' the features of construction and combinationof parts here'- inafter described and claimed. 7

In the drawings, Figure l is a top or plan view looking down upon theobliquely-dis-v posed feedingtable; Fig. 2, a front view of the movableframe carrying the knife and. formingmechanism; Fig; 3, a view of theforming plate; Fig. 4, a cross-sectional view of the entire device,showing the relative disposition of the various elements; Fig. 5, 'a'rear 'view of the movable frame of Fig; 2, and. Figs. 6,

7, and 8 are detail viewsof the operative mechanism in differentrelations; and Figs;

9 and 10 views of'a feed mechanism which may be used, if desirable.

The machine is constructed with'a frame consisting of two supports A atsuitable distances from one another, each support being provided withfeet a, uprights a, and an obliquely-disposed top rail A, preferablyprovided with an inwardly-turned flange or ledge a upon which is carriedan obliquely-disposed feeding-table B, which is held in place on theledge and regulated thereon by means of set-screws b, carried by ears(2, (best shown ing sizes.

between them.

in Fig. 4,) and by means of bolts b extend= ing through side walls ofthe top rail of the frame. Upon the feed-table are arranged a pair ofguide-rails B, provided on their exterior with slotted arms b throughwhich project screw-threaded bolts 1), threaded into holes Win the faceof the table, which arrangement enables the guide-rails to be adjustedto accommodate metal plates of vary- At right angles to the top rail ofthe frame are two guideways 0, below which are supporting-arms C,terminating in inwardly turned ears 0, through which are screw -threadedbolts 0 for the purpose of regulating the mechanism supported by andupon the arms 0'. Between the guideways is carried a movable frame D,preferably composed of a single casting, having at its ends 'slides d,operating Within the guideways O and regulated therein by means of aset-screw d, contacting a hardened plate d within the guideways.Extending between the slides isa lower rail or support (1 provided withears d formingbearings for the driving-rods which actuate the movableframe. Across the top of the frame extends a plate o'r bar E, at rightangles to which is a plate or bar E, below which is a projection (2,while on the opposite side is a ridge or ledge e. 7 Attached to theupper face of the projection e is a movable cutting-knife or shears F,coacting with a fixed knife or shears F, attached to the forward loweredge of the feed-table, and attached to the lower front face of theprojection 8 and. normally projecting slightly be low the edge of themovable knife or shears is a forming-plate F secured in place by meansof boltsfand having the same line of travel as the movable knife, bothknife and forming-plate being attached to the same movable frame. Belowthe knives and having the same angle of inclination as to feedtable is aplaten G, having in its body'a slot g and being recessed in its upperface to receive the upper and. lower platen-plates g and g the latterbeing preferably adj ustable to regulate the width of the slot formedThe platen is held in place and regulated by means of set-screws 0,heretofore described, although it may be held in place in any desirablemanner. The platenplates, as shown in Figs. 6 and 7, are recessed ontheir under faces, forming projecting flanges 9 the purpose of whichwill hereinafter appear.

Contacting with themovable knife or shears is a contact-plate 11,provided on its upper edge with slotted arms h, which are in alinementwith and rest upon ribs 77., formed on the face of the movable frame andslidably held in place thereon by means of set-screwthreaded bolts 7L2,allowing the plate H to travel up and down, its travel being limitedonly by the length of the slots in the arms h. The contacting-bar isprovided on its face with recessed ears h in alinement withrearwardly-projecting arms h on the movable frame, and a rod 72;",encircled bya coil-spring 7L6, extending obliquely downward from thearms into the recessed ears and being fixedly held by the arms, enablesthe contact-bar to be slid back against the pressure of the springs,thereby changing its position with respect to the cutting-knife withwhich it cooperates. Within recesses I in the contactplate are a seriesof pins I, each provided with an enlarged head i, in contact with whichis a coil-spring 'i', regulated by means of an adjusting-screw i andthese pins are arranged to normally project below the edge of thecontact-plate and adapted to be pressed back thereinto against thepressure of the springs when the contact-plate is brought down on thesheet of metal being operated upon.

Upon the face of the lower platen-plate is a forming-stop J, providedwith downwardlyprojectiug slotted armsj, through which projectscrew-threaded bolts j, which enables the adjustment of the forming-stopto meet the requirements of its use. On the opposite side of the slot inthe platen is located a cutting-stop K, supported at its ends byangularsupports K, termiuatingin slotted arms It, held in position bymeans of bolts 7r, which enable the adjustment of the cutting-stop tomeet the requirements of its use. Adjacent to the lower side of thecutting-stop is a series of guide-pins L, each provided with a pin Z,arranged to contact with the upper face of the cutting-stop, and theguide-pins are each provided with a recess l, into which projects a pinZ and behind the guide-pins and within the recess L in which theyoperate are arranged coil-springs i which normally tend to hold theguide-pins in the position shown in Fig. 6 below the edge of theforming-plate with the stop-pin I out of contact with the cutting-stop;but as the forming-plate descends the travel of the guidepins is limitedby the stop-pins Z, so that the formingplate passes down below the edgeof the guide-pins and into the slot between the platen-plates.

Directly below the movable knife or shears is a series ofsupporting-pins M, carried by a rod or rail M, which latter is supportedby means of a coil-spring m upon the lugs m on the rail D of the movableframe. The upper projection of these supporting-pins is limited by thetravel of the rod or rail M, so that they never project above the planeof the stationary knife or shears; but on the downward stroke of themovable frame after the tension on the coil-spring has been released thesupporting-pins will travel downwardly a suitable distance to bring thembelow the plane of the platen-plates. The travel of the supporting pinsis regulated by means of slotted fingers N, adjustably held in place onthe movable frame by means of screw-threaded bolts n, and these fingersare adapted to contact with studs 12' on the rod or rail carrying thesupporting-fingers, by which arrangement the withdrawal of thesupporting-pins may be regulated to begin at the proper time.

The movable frame is operated by means of a rod 0, terminatingin aneccentric 0, carried by a shaft 0, and, as shown, the shaft is operatedby a driving-wheel P, which imparts motion to the shaft through a clutchP of any suitable construction, which clutch is operated by means of afoot-treadle P or by any other suitable means.

It will sometimes be found advantageous to provide a feeding device toaid in discharging the strips of metal after they have been out,especially the last few strips, which are not readily forced from thecutting-knife by reason of the light weight of the sheet upon them, and,if so desired, the feeding devices illustrated in Figs. 9 and 10 may beemployed. This consists of a small contactplate Q, set edgewise withinthe guide-rails B, having its projecting end q beveled to form acam-surface. The contact-plate Q is provided with pins q, operatingwithin slots g in the guide-rails, and behind the contactplate isinserted a coil-spring 1 which normally projects the cam-surface qbeyond the end of the guide-railand in the line of travel of thecontact-bar H. To the bottom of the contact-plate is attached a flatthin feed-plate (1 which projects inwardly and forwardly of theguide-rail and over which the sheet of metal travels as it passes downto the cutting-knife. As the contact-plate descends with each stroke itstrikes the cam-surface and forces the plate Q and the feed-plate q backagainst the tension of the coil-spring,

which position they occupy during the out- When, however, the strip.

ting operation. has been out and the contact-bar rises, thecontact-plate will be released and will fly back into place, togetherwith the feed-plate, forcing the strip off and away from the knivespreparatory to permitting the operation. As the sheet is held down thefeed-plates, which normally project under the cuttingknife, serve tosupport and position the advancing sheet until the same has been clampedby the descending contact bar or pins when the feedplate is forced backout of the way of the v knife.

feed-table and serve to guide the sheet ofmetal as it slides therefrominto contact with the cutting-stop, retreat as the knife descends andassume the position shown in Fig. 7, al-

lowing the cut strip to pass down under the cutting-stop and under theguide-pins L into place against the forming-stop prior to the descent ofthe forming-plate. On the next descent of the movable frame thepreviously-- cut strip will be in position against the forming-stop andthe sheet of metal on the feedtable will have traveled down under themovable knife and against the cutting-stop, so that with the descent'ofthe frame the strip previously cut will be forced down through the slotbetween the platen-plates by the forming-plate at the same time that anew strip is being cut from the sheet of metal.

The projecting lips or flanges on the upper platen-plates prevent theformed strip from being withdrawn through the slot and serve to clearthe forming-plate for its next succeeding stroke; The cutting-stop maybe located to determine the width of strip desired, and the formi-ngstopmay be advanced or withdrawn to regulate the bend or crease desired inthe strip, so that the same may be formed to havethe crease in themiddle or at one side, if so desired.

As the sheet of metal slips down by gravity it will be found that therewill be a slight ex cess of metal, and it is desirable that this excessof metal be left on'the lastistrip rather than out therefrom, makingthis last strip too wide rather than toonarrowQfor the reasonthat if outOK it might slip down and become clogged in the operating-gear of themachine by reason of its extreme narrowness in comparison with precedingstrips. The pins 1' in the contact-plate are'so arranged that they willcontactthe sheet of metal after the contact-plate has been withdrawntherefrom by reason of the springs by which they are actuated. If, forinstance, the machine is regulated to cut strips a half-inch in widthand the last strip of metal is five-eighths of an inch in width and thedistance between the pin 1 and the lower edge of thecontact-plate isonefourth of an inch, then this last strip of metal, which isfive-eighths of an inch in'width, will not be contacted 'by the pinsafter it has slipped down against the cutting-stop, as shown in Fig. 8,and will fall down and be formed as are the other strips. If, however,

the strip be one inch in width, then it will be contacted by the pinsand held while the knife 1 descends and cuts the strip into two pieces,each the proper width of one-half inch.

It will thus be seen that the operation of the machine is entirelyautomatic, that the parts are all adjustable to cut strips of vary- 'ingwidths, and that the arrangement is of simple construction by reason ofthe fact thata single stroke of the movable frame cuts one strip andsimultaneously forms the next preceding strip, obviating thenecessityfor separate and distinct forming mechanism.
